“Neylan, the head of PTSD research at the San Francisco Veteran’s Administration, showed one area of the brain, that’s affected by PTSD. It’s called the hippocampus. It looks like a little jelly roll and is responsible for memory.”

“High resolution brain scans show that people with PTSD have a smaller hippocampus, by 11 percent on average.”

“Some other key findings to be released at the conference, suggest that older PTSD veterans were almost twice as likely to develop dementia, they have two to three times higher risk of heart disease, and have a higher risk of death after surgery.”
